INCUBATOR.

$PECIFICATION forming part of Letters Patent No. 369,682, datedSeptember 13, 1887.

Application filed January '7, 1887.

To all whom, it may concern.-

Be it known that I, FREDERICK BIVEN, a citizen of the United States,residing at Stockton, in the county of San Joaquin and State ofCalifornia, have invented certain new and useful Improvements inIncubators; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

My invention relates to incubators for the artificial hatching of eggs;and it consists in a novel heating apparatus, Ventilating-tubes, and aself egg-moistener, and in such other de vices as will be described inthe specification and pointed out in the claims.

To more properly explain my invention reference is had to theaccompanying drawings, forming a part of this specification, in which-Figure 1 is a perspective view of the incubator with the cover removed.Fig. 2 is a detached view of the cover and ventilating-tubes. Fig. 3 isan elevation of the heatinglamp and a portion of the heating apparatus.Fig. 4 is a section of the same through line :0 m, Fig. '3.

Similar letters of reference indicate corresponding parts.

The incubator-chest A is mounted upon suitable legs, and is suppliedwith aside door, a. The eggs, arranged in suitable trays, are placedupon the bottom of the chest A, the door a being opened for suchpurpose. The heat is supplied from a lamp, I, the chimney of which isinserted in an angular tube, D, the vertical portion of which and thelamp I are outside the box A, while the horizontal section above the boxA is attached to and discharges into an oval top heating-chamber, (3,which is lo cated just beneath the removable cover B of the chest A. Thechamber 0 is supplied with an escape-pipe, d. The pipes d and D alsoserve to support the chamber 0 in its position. At each corner of thecover B is a ventilating tube, b, which, when the cover is placed uponthe chest A, is distant about an inch from the floor of the chest, thusinsuring Serial No. 293,696. (No model.)

chest A, just below the tube D. In one corner of the deflector E, Iprovide an opening, which is shut off from the chest A by an angularstrip of tin, e, on one side and end, so that no heat passes downward.

In the inclosure formed as above described is located the tube of aheat-regulator of any desired style, but preferably that shown inLetters Patent No. 323,556, granted to me August 4, 1885.

To insure a proper moisture, a water-pan, F, is attached to the side ofthe chest A, just beneath the horizontal section of tube D. A tin tube,G, encircles the vertical portion of tube D, and has an open lower end,permitting the free circulation of air in it and about the tube D. Thetube G is inclosed by a wooden box, H, to prevent the cold air fromcoming in contact with the outside of tube G. All the tubes and hot-airchamber are eonstructed of sheet-tin.

By means of the above-described devices I am enabled to furnish anincubator with a supply of properly-moist air and diffuse it equallyover the eggs and insure perfect ventilation, so that the eggs arehatched in one or two days less time than nature requires.

I am aware that it is not new to provide a heating-ehamber in the upperportion of an incubator and the cover with depending ventilating tubesor pipes, and that water-evaporating pans have also been used.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In an incubator, the combination, with the chest provided with ahinged door and a removable cover having air-tubes at its corners, ofthe arched heater having pipes D d, a shield, H, and a lamp, and thehorizontal deflector E, extending partly beneath said heater,substantially as and for the purposes described.
